its proper cutting angle and means for causing the device to move the .saw in either direction as desired.

This invention also consists in certain other features of construction-and in the combination and arrangement of theseveral parts, to be hereinafter fully described, iil lustrated in the accompanying drawings and specific-ially pointed out in the appended claim.

In describing my invention in detail, re-

ference will be had to the accompanying plate 5 being supported by a part of the casing and the posts. A shaft 6 passes through the casing 3 and has at one end thereof a hand wheel 7 and its other end a grinding wheel 8. The wheel 7 is provided with the ring gear 9 and stub shafts 10 and 11 are journaled in the casing 3 and have pinions 12 thereon which mesh with the gear 9. Thus the stub shafts 10' and 11 will be rotated when the main shaft is rotated from the hand wheel. A crank disc 13 is connected with the inner end of each stud shaft.

of the upper shaft. A guideway 15 is formed on the front end of top plate 5 and a block 16 is slidably mounted therein. This block carries a shaft 17 which is provided with a socket 18 for receiving a saw file 19 and the inner end of said shaft is pivoted as at 20 to a pitman 21 which is fastened to the crank pin of the upper disc 13. Thus the file is reciprocated by the rotary move- A cam 14 is connected with the crank disc anentofthe crank disc and in order :to

Thewparts areinormally heldiin lowered position by HIGQHSrO'f the spring 25. A saw holder 26 has. a :slot 27 :therein to receive a :sawfsuch as shown at A, the saw being .clampedzin thelholder by means of the thumb:nuts ;28 onsthe bolts '29. .The holder is slidably mounted ;in 1a guideway member 30 :WlllC-ll is-pivoted :at

An arc-shaped brace 32 has its ends connected with the ends of the member 30 and this brace passes through the clamps 33' on the base so that the parts can be adjusted to the desired position and then clamped in this position. A block 34 is pivoted to the base plate and has a guideway therein for receiving a head 35 to which the caliperlike arms 36 are pivoted, the arms being normally held against the stop pins 37 on the block by the spring 38 which connects the two arms together. These arms act as dogs on the ratchet wheels 39 which are mounted on a vertical stub shaft 40 to which a gear 41 is fastened which engages a rack 42 on the saw holder 26. The head 35 is connected by the turn-buckle device 43 with the pitman 44 which is connected with the crank pin of the lower crank disc. The

' block 34 can be adjusted by means of a screw turn the shaft 40 in one direction and thus cause the saw holder to move in one directlon while when the other ratchet 1s in actuation the shaft is turned in another diening various tools.

Opposite direction from that given-it by the first ratchet. V p

As will be seen by turning the hand wheel the saw holder will be given a step by step movement and the file will be reciprocated, the file on one stroke engaging the teeth and on lts other stroke being raised out of engagement with the saw so that the 'saw can be moved by the ratchet means above described.

sharpened by simply turning the hand wheel Thus the saw can, be

and the parts can be adjusted to give the cutting edges of the teethithe proper angle. The grinding disc 8 may be used for sharp- It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire itto be understood that I may make changes inthe construction and in the combination and arrangement of the several parts, provided that such changes .fall within the scope of the appendedsclaim.

\Vhat I claim is w 1 A saw filing machine comprising a supporting frame, a hand wheel having a shaft journaled in the frame, a gear on the wheel, a pair of stub shafts, pinions thereon engaging the gear, a crank disc on each stub 30 haft, a slidable block on the frame, a file carrying shaft connected with the block, a pitman pivoted to the shaft and connected with the upper crank disc, a cam on said crank disc, a lever pivoted to the frame and engaged by the cam and having a part for engaging the block for raising the same to lift the file, a saw holder, a guideway for ,the same, means for adjusting the guide way on the frame to place the saw at any desired angle in relation to the file, arack on the holder, a shaft in the frame, a pinion thereon engaging the. rack, a pair of oppositely arranged ratchets on the shaft, a

head, a pair of dogs thereon for engaging the'ratchets, a block pivotedto the frame and moved about a vertical axls and having a horizontal guideway therein in which the J. R. PHELPS.
